(but not 8085) op codes‚ but included 80 more‚ instructions. The register set was doubled‚ with two banks of data registers that could be switched between. This allowed fast operating system or interrupt context switches. The Z-80 also added two index registers and 2 types of relocatable vectored interrupts. The thing that really made the Z-80 popular in designs was the memory interface - the CPU generated its own RAM refresh signals‚ which meant easier design and lower system cost‚ the deciding factor

PC TO PC FIBER OPTIC COMMUNICATION [pic] Submitted By: lex INTRODUCTION DEFINITION The project PC to PC fiber optic communication deals with data transfer from one computer to another. It uses C programming and the serial ports of the PCs. The ports are programmed in C. We use MAX 232 to convert RS 232 logic to TTL logic and then an optical transmitter circuit to transmit data via fiber optic cable. The optical transmitter circuit has a LED which is matched as far the cable
